hi, yes - with this two functions (get-posititon & inserting-on-bar/beat*) you will have a lot of possibilities... 1) post-processing an OMN without changing the global time structure 2) working with "strukturnetze" (lachenmann) 3) countrepoints 4) idea of palimpsts .... ...so, perhaps OPMO could code it smarter then me (that's not complicated :-))? ... i try to do an example today with something like a "strukturnetz"

Hi, could be also useful for counterpoint ! Great ! S.

Hello people! This is a relatively recent work that I composed with Opusmodus. A septet... Alto Flute, Clarinet, Trombone, Viola, Violoncello, Piano, Percussion This is a live recording from the premiere at the Trieste Prima Festival and is by Ensemble MD7 conducted by Steven Loy.

Small duet for Violin and Piano from 3 Images pour Violon et Piano. The 2 others duet are in progress. I've used some midi pre-recorded material prepared and edited in Logic before importation into Opusmodus and after import, i've processed this material with opmo functions and export back to Logic X for final edition and final score edit.

Hi, I was wondering how to get an octave treble clef and the correct transposing notation when writing for guitar. At the moment my def-score look like this: (def-score Crossing_Waves (:key-signature 'chromatic :time-signature timesigs :tempo 72 :layout (guitar-layout 'inst)) (inst :length lengths :pitch pitches :velocity dynamics :channel 1 :sound 'gm :sound 'acoustic-guitar-nylon) Notation is in treble clef in one system as it should, but as sounding pitch without the 8 under the treble clef. Kind Regards, Erik

New: POSITION-ATTRIBUTE ATTRIBUTE-MAP EVENTS-ANALYSIS OM Developer/Predicates: 12TONEP CONTAIN-ATTRIBUTEP ATTRIBUTE-SYMBOLP EVENT-RESTP POSITION-ATTRIBUTE: The function POSITION-ATTRIBUTE returns a lists of bar numbers and positions values of a given attribute in a sequence. This function is a companion to the ATTRIBUTE-MAP function. Examples: (setf mat '((h. f6 mp stacc) (-q h a4d2 p fermata e fermata) (e. a4d2 p - h e4g3 mf s fs6 p e c6 mp ten e. cs4 p tie) (e cs4 p q gs5eb6 h b2 p stacc e stacc) (q b2 p tie s q f6a4 mf -e q. d2 p ten) (h d2 p tie s q e4 mp tr2 s tr2 -q. q f4 stacc) (s f4 h. a3gs5 p fermata -e. -s))) (position-attribute 'fermata mat) => ((2 (1/4 3/4)) (7 (1/16))) (position-attribute '(fermata stacc) mat) => (((2 (1/4 3/4)) (7 (1/16))) ((1 (0)) (4 (3/8 7/8)) (6 (5/4)))) ATTRIBUTE-MAP: The function ATTRIBUTE-MAP aligns attributes of one sequence (instrument) to another sequence.

thanks for the quick answer! So the floating point numbers velocity ranges from 0.1 to 0.99 or how do it relate to the 1-127 midi steps? I want to create an as-smooth-as-possible crescendo from the lowest possible value to the highest over x steps.. Can you point me to some more information about 'floating point numbers velocity'?
